LANTERN.

SPECIFICATION forming part of Letters Patent No. 259,170, dated June 6, 1882. Application filed Martino, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. KINNEY, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Lanterns; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a perspective view; Fig. 2, a vertical central section; Fig. 3, a transverse section on line as w.

This invention relates to an improvement in lanterns, with special reference to that class in which the air to support combustion is led to the combustion-chamber through tubes opening near the top of the lantern, commonly called tubular lanterns,"

In alllanterns as heretofore constructed the base has been-substantially semicircular in form, and necessarily so much larger than the burner that it has cast a shade below over a very large extent. Hence with such lanterns it is difficult to observe objects below it without tipping the lantern, and such tipping generally smokes or breaks the globe.

The object of my invention is to construct the base of the lantern so as to cast but very little shadow downward; and it consists principally in a central wick-chamber surrounded by a concentric oiLchamber, combined with the tubes opening from above leading downward and into said air-chamber, with an oilchamber between the said air-tubes and on opposite sides of the air-chamber, communicating with the wick-chamber, as more fully hereinafter described;

A is the wick-chamber, which consists of a cylindrical wall, a, of sufficient diameter to receive the wick B, and constructed at its upper end to receive the burner C, which may be of any of the usual and well-known constructions. The wick-tube is surrounded by an air-chamber, D, the cylindrical wall a of the wick-chamber forming the inner walland the concentric cylinder d forming the outer wall, as seen in Figs. 2 and 3. This outer wall extends up and so as to be covered by the skirt or chimneyrest e'of the burner.

E E are the air-conducting tubes, which receive air from above in any of the usualor well-known methods for supplying air thereto. These tubes lead downward and open into the air-chamber D, as seen in Figs. 2 and 3, and by which air is led to the air-chamber, thence up through the air-chamber to the burner, to support combustion. The space F each side the air-chamber and between the air-chamber and the tubes is inclosed by acasing, f,'with a tight cover, h, to form the oil-fount, and which form wing-like projections each side the central cylindrical portions,narrower than the diameter of that central portion. To open communication between the two parts F of the fount, a -tube, t, leads from one to the other, as

seen in Fig. 3, and that the oil may be sup this application, it only being essential to this invention thatthere shall be some device above it to support the upper end of the chimney and of the tubes.

The chimneyrest is perforated in the usual manner to .permit a portion of the air admitted through the tubes to pass into the chimney outside the burner; but, if preferred, the chime ney-rest may have openings outside the airchamber D, so that the air for the supply of the chimney outside the burner may come from outside the lantern; but I prefer to take the entire supply of air for the support of combustion through the burner, as well as outside the burner, from the air-chamber and down through the tubes E, because of the better results which I thereby attain.

As the shape and size of the base of the lantern are not such as to give permanency to the lantern when standing upon its base, I construct an open or ring-shaped base. (See Fig. 1.) This is best done by bending two pieces of wire into semicircular form, extending the two ends inward, and soldering them together and to the base, as shown. This wire or open base does not materially interfere with the downward light, but yet affords a firm support for the lantern.

It will be understood that the lainp-fount is filled in the usual manner through a fillingopening, a.

As it is necessary to supply air to the fonnt in order that a proper flow of oil may be maintained, I arrange a small air-tube, 1*, extending up from the top of the fount, and which is at all times open.

Instead of making connection between the two parts of the fount by means of the tube 1', it may be otherwise accomplished-as, for instance, the air-cha-mber may terminate a little above the bottom, so as to leave an annular space between the bottom of the central portion of the air-chamber, through which the oil will pass into the wick-chamber-it only being essential that there shall be some connection between the two sides.

By this construction I am enabled to contract the base of the lantern to such an extent that very little shadow is cast by the base. The central portion is of less diameter than the burner, which is of itselfvery little, if any, larger than is required for a common chimney, and that part which extends to each side is little, it any, thicker than the tubes which supply the air, and occupies so little space that very little shadow will be cast therefrom, because the flame itself will be greater than the thickness of that portion.

I claim- 1. The combination ofa central wick-chamber, a surrounding air-chamber, a burner set into said wickchamber, opening to said air-chamber, and tubes leading from above to conduct air to the said air-chamber, the space between said air-tubes and outer wall of the air-cham- 5 her inclosed to form an oil-fount at each side, communicating with the wick-chamber, substantially as described.

2. The combination of the central wickchamber, surrounding air-chamber,a burner upon said wick-chamber, constructed to receive air from said chamber into the combustion-chamber and also into the chimney, and air-conductin g tubes arranged to lead air from above downward and into said combustion-chamber, the space at each side between the outer wall of said air-chamber and the tubes inclosed to form an oil-fount communicating with the wickchamber, substantially as described.

3. The combination of a central wick-chamber, a surrounding air-chamber, a burner set into said wick-chamber, and tubes leading from above to conduct air to the said air-chamber, the space between said air-tubes and outer wall of the air-chamber inclosed to form an oil-t'ount at each side, communicating with the wick-chamber, with an open base upon which the said parts rest, substantially as described.

4. The combination of a central wick-chamber, a surrounding air-chamber, a burner set into said wick-chamber, opening to said air-chamber, and tubes leading from above to conduct air to the said air-chamber, the space between said airtubes and outer wall of the air-chamber inclosed to form an oil-fount at each side, communicating with the wick-chamber, with a base made from wire and upon which the parts rest, substantially as described.

. 5. In a lantern, the combination of the central wick-chamber, surrounding air-chamber, and tubes arranged to conduct air to the said air-chamber, with a fount constructed in winglike projections on opposite sides of the airchamber, substantially as described.
